EGG-SHELL REMOVER.

Specification of Letters Patent.

Patented July 5, 1910 Application filed April 6, 1910. Serial No. 558,860.

To all whom it may concern:

Be it known that I, An'ron UnLIn. a citizen of the United States, residing at Charleston. in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Eg Shell Removers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in kitchen utensils and more particularly to egg-shell removers.

The object of my invention is to provide a simple device by means of which the shell may be removed from a cooked or partially eookcd egg.

In the accompanying drawing, I have shown the preferred embodiment of my invention. It will be understood, however, that many modifications may be made therein; without departing from the spirit or scope of the invention.

In said drawing, l igure 1 is a perspective view of the complete device as app ied to use. Fig. 2 is a central sectional view through the complete device. Fig. 3 is a sectional view through a portion of the device as seen on line 3--3, Fig. 2. Fig. 4 is a bottom plan view of a portion of the device, and, Fig. 5 is a perspective view of a portion of the device.

vln the embodiment of the invention shown, l provide a base plate 1, to one end of which is secured a tubular member 2. Said member 2 forms the cylinder ,of an air pump or compressor 3. Said pump 3 is provided with a closely l'itting plunger 4 adapted to be reciprocatial therein. A rod 5 is secured to the plunger t and an operating head 6 is secured to or formed integral with said rod. A spring 7 surrounds the rod andis disposed between the head (3 and the cap 8 of the cylinder 2 and tends to maintain the rod and plunger in the position shown. Also secured to the base 1 is a member 9 which is preforably circular in cross section and a. flange l0 surrounds the member 9 near its upper end, said flange being cut away at intervals for a purpose to be hereinafter clearly set forth.

Secured across the upper end of the member 9 is a diaphragm 11 preferably formed of rubber. This diaphragm has a central,

circular opening therein and may be secured in place by means of a wire or band 12 which encircles the ed e thereof and the outer sur;

face-of the mom or 9. Secured in said mem-' her 9 and extending verticall therein is a erforating member 13. San? member may )e secured in place in any desired manner or preferably b being provided with a foot portion 1 1a apted to be forced between the base 1 and a semi-partition 15 secured horizontally in the member 9. The manner of fastening the perforating member 13 in place will be clearly understood by reference to Figs. 2 and 3, where it will be seen that the same is removably secured so that different shapes and sizes of perforators may be used.

Although I have shown a spear-shaped perforating member mounted in the chamher, I do not mean to limit myself to this showing and may use any form of perforat A cap member comprisin a ring 16 and a" top portion 17 is provided for the member 9. Inwardly projecting lugs 17 a are provided at intervals at the lower edge of the ring 16. Said lugs are so formed as to coincide With the cutaway portions of the flange 10 so that said cap member may be placed on the member 9 and partially rotated to bring the lugs 17 beneath the flange 10 to prevent the removal of said cap-like member. The top 17 is provided with a central aperture and the material adjacent the aperture is depressed, as clearly shown in Fig. 2, so that when the cap member is in position, the diaphragm will be engra ed by the lower edge of the depressed portion. The ring portion 16 of the cap member is of greater width than the distance between the topof the member 9 and the flange 10, so that the cap member may be forced downward against the tendency of the diaphragm to hold it in its upward position. The pressure upon the diaphragm, being equal around the aperture therein, will cause a uniform stretching of said dia. )hra m when the cap member is depresse am a uniform enlargement ofthe aperture there- 1 in, as shown in dotted lines in Fig. 2. The

- member 9 and the cylinder 2 are connected by means of passage-way or duct 18.

phragm, WlllCh has been stretche When it is deslred to remove the shell from an egg, the smaller end, or the end opposlte the- .end having the air bubble, is

I placed against the gap member and forced ow nwardly, mov1ng the cap member to its lowest position and'at the same time causing the shell to be broken by the perforating member'13. The perforating member 13 is preferably made spear-shape, as shown, so that the contents of the shell will be held thereby. Upon releasing the eg(g, the diawill contract and tightly grip the end of the egg.

The head 6 is now quickly depressed, causing a volume of air to passfrom the cylinder 2 into the chamber 9 and thence through the aperture in the end of the egg. Theshell 'will be. broken away by'the air pressure, leaving the contents of the egg held by the spear-shaped end of the perforating member.

I wish to call. attention to the screen 19 which is laced in the passageway 18 and conforms in outline thereto to prevent particles of shell, etc., from beingsucked back into the pump when the plunger is released. What I claim is 1. In an egg-shell remover, in combination, means to engage one end of an egg, means to perforate the shell, and means whereby air may be forced into said shell.

2. In an egg-shell remover, in combination, a chamber for receiving one portion of an egg, means to perforate the shell thereof and means to compress-air in said chamber.

3. In an egg-shell remover, in combination, a chamber, a resiliently supported member at one end thereof for receiving tion, a chamber having its upper end open, a diaphragm across sald 0 en end, said diaphragm having a central y disposed aperture therein, a cap for the upper end of said chamber, said cap having a centrally disposed aperture of greater diameter than the diaphragm aperture and having a depending port1on around said aperture adapted to rest against the diaphragm, said cap having a limited downward movement,'a perforator, and a pump for compressing air in said chamber.

' 6. A device for removing the shell of an egg [X -means of air under pressure.

7 e g-shell remover, comprising means to utilize compressed air to strip the egg of its shell. I

8. An egg-shell remover, com rising a chamber for receiving the end 0 an' e g,

means to perforate the egg-shell, a ump or compressing air into said cham er and means to prevent the entrance of extraneous matter into said pump.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
